 Some Linux distributions like GoboLinux and moonOS have proposed alternative hierarchies that were argued to be easier for end users, though they achieved little acceptance.In 2004, Microsoft initiated its "Get the Facts" marketing campaign, which specifically criticized Linux server usage.In particular, it claimed that the vulnerabilities of Windows are fewer in number than those of Linux distributions, that Windows is more reliable and secure than Linux, that the total cost of ownership of Linux is higher (due to complexity, acquisition costs, and support costs), that use of Linux places a burden of liability on businesses, and that "Linux vendors provide little, if any indemnification coverage."
